EL devices generally have a plate shape and have a basic structure of a laminated structure in which an insulating layer and a light emitting layer are interposed between a back electrode and a transparent electrode film. Lead terminals 6 and 6' are attached to the rear surface, and conventionally, as shown in FIGS. 6 and 7, lead terminals 6 and 6' are formed by pattern-forming a metal film laminated on a synthetic resin film 5 by etching or the like. The device is connected to the electrode 1 and the transparent electrode film 2, respectively, and the entire device is covered with a moisture-proof film 8. Furthermore, a notch 7 formed by cutting out the synthetic resin film 5 is formed between the lead terminals 6, 6' between both terminals.

提供することを目的とするものである。 In such a conventional EL element, the lead terminals 6, 6' are formed integrally with the synthetic resin film 5, so that the bending strength is particularly improved by reinforcing the lead terminals 6, 6'. However, as is clear from FIG. 7, the notch 7 is not entirely covered by the moisture-proof film 8, but a portion thereof is exposed from the moisture-proof film 8, so that the lead terminal 6 and 6' could not be sufficiently reinforced by the moisture-proof film 7. The present invention has lead terminals 6,
It is an object of the present invention to provide an EL element in which the mechanical strength of the element 6' can be improved, thereby improving the reliability of the element.

In the EL element according to the present invention, as shown in FIG. The element main body is completely covered with the moisture-proof film 8, and the periphery of the moisture-proof film 8 is thermocompressed, thereby sealing the element body therein. Therefore, the lead terminals 6, 6' are reinforced by being covered with the moisture-proof film 8 in the portions adjacent to the notch 7, and in the portions not covered by the moisture-proof film 8, the lead terminals 6, 6' are reinforced with the moisture-proof film 8. Since the lead terminals 6 and 6' are reinforced by the resin film 5, there are no locally low bending strength parts as in the conventional case, and sufficient mechanical strength can be ensured throughout the lead terminals 6, 6'.

1 to 5 are diagrams showing one embodiment of an EL element according to the present invention. In the figure, 1 is a back electrode made of Al etc., 2 is a transparent electrode film made of polyester film etc. on which indium oxide etc. is vapor deposited, and 3 is a high dielectric material such as barium titanate whose dielectric constant is increased by cyanoethylation etc. The material was dispersed in a thermoplastic binder and made into a paste using a solvent, and then formed into a paste using a screen printing method.
4 is a luminescent layer coated with a paste made by dispersing a phosphor such as ZnS in a thermoplastic binder; 6 and 6' are as shown in FIGS. 4 and 5. Aluminum is formed on a synthetic resin film 5 such as polyester by a method such as vapor deposition or lamination, and then patterned by a method such as photoetching or printing etching, and a plurality of pairs are formed in parallel on the synthetic resin film 5. 7 is a synthetic resin film 5 between both terminals 6, 6' for each pair of lead terminals 6, 6'.
is a notch formed by cutting out a predetermined length from the edge by punching such as a press, and after the lead terminals 6, 6' and the notch 7 are formed, the synthetic resin film 5 is cut out by the l-l wire. They are cut along the respective lines. 8, a connecting portion 9 is formed by cutting out the back electrode 1, the back electrode, the insulating layer 3, and the light emitting layer 4 from the lead terminals 6, 6' formed on the cut synthetic resin film 5. After being connected to each of the transparent electrode films 2, the film is a moisture-proof film that covers the entire element so that the notch 7 enters at least a predetermined distance a, and the peripheral edge is bonded by thermocompression.

更に増長され得る。 Since the EL element according to the present invention is constructed as described above, even though the notch 7 is provided, the lead terminals 6 and 6' are supported by the moisture-proof film 8 in the vicinity of the notch 7. Since the other parts are reinforced by the synthetic resin film 5 as in the conventional case, the bending strength, twisting strength, etc. can be improved throughout. Therefore, the reliability of the entire device can be improved by improving the mechanical strength. Moreover, this notch 7 allows the synthetic resin film 5 to
Since the lead terminals 6 and 6' are bifurcated, when connecting the lead terminals 6 and 6' to the respective electrodes 1 and 2, they can be easily connected without being subjected to excessive deformation. Since no mechanical strain or the like occurs in the portion sealed by the moisture-proof film 8, the sealing is complete, and as a result, the intrusion of moisture etc. from the outside can be effectively prevented. In addition, when covering with the moisture-proof film 8, the a-width part (see Figure 1)
Such moisture proofing can be further enhanced by punching or other means to form a plurality of holes with a diameter of about 100 to 200 μm.
